Abstract
The effect of boron content (4-8 at%) on the microstructure of Pr-Fe-Co-B-Nb alloys has been investigated using scanning electron microscopy and energy dispersive x-ray analysis. Permanent magnets were prepared from cast and annealed alloys using the hydrogenation, disproportionation, desorption and recombination process. The magnetic properties of magnets with the composition Pr14Fe69.9âxCo16BxNb0.1 were assessed using a permeameter technique. It has been shown that annealing and boron content have a dramatic effect on the microstructure of the alloy and also on the magnetic behaviour of these bonded magnets.
